ATTACHABLE FEED non WRINGERS.

Application filed January 31, 1925. Serial No. 5,960.

The invention seeks to simplify and improve the means for attaching anendless, apron feed to domestic wringers such as are mounted ontubs andsmall washing machines. It aims to present such an appliance in a formwhich may be readily accommodated to familiar forms of wringers withoutmodification of the framing andy construction, arrangement andcombination of parts will be more readily understood from the followingdescription and from the accompanying drawings, in Which- Figure 1 is aside elevation of a wringer equipped with my invention.

Figure 2 is a front view of the wringer.

Figure 3 is a vertical section of the adjustable bearing and bracket.

Figure 4 is a side elevation of the last mentioned bracket. i

There is illustrated a wringer 10 of familiar construction, includingtwo main frame uprights 11, between which extend the lower and upperrolls 12 and 13, which.

may be mounted and operated in anyl of the various ways familiar in theart. Uusually in these appliances the lower roller is on a fixed axisand they upper adjustable or yieldable to variousthicknsesses ofmaterials passing between the rolls.

The uprights 11 inthe particular form of wringer shown are customarilyformed of wood, but my device is also adaptable to metal frames as well.

Two brackets 14 are provided on one side of the wringer each comprisinga stamping of sheet metal somewhat in the shape of an ordinary straphinge with a butt part. That is to say, the outer part 15 of the bracketis somewhat Vsh'aped in the plan of the blank,

while a rectangular base 16 is formed thereon of the same width bentsharply at right angles tothe part 15,vapertured andcsecured to thewringer by screws 17. Near the extremity of the bracketa collar 18 isformed therein by extrusion, receiving a bushin 19 with 'a pressed fit.The nmedial longitudinal axis of the bracket is approximatelyhorizontal. The width of the blank at the base 'preferably does notexceed the diameter of the roll ofthe wringer upon which the device isto be used, for a reason which will appear. Between the brackets 14there is mounted-a roller 20 having trunnion's fitted to the bushings18. This roller may be of metal or wood and-requires no special facingsuch as rubber or other cushion or elas- .tic material. The Width of theouter ends of ioaolo' the brackets is as much less than the diameter ofthe roller as practicable.

At the opposite side of the wringer, slotted brackets 21 are mountedsimilar in size and external measurements to the brackets 14. A'long-itudinal horizontal slot 22 is Aformed in each, extending from nearthe outer end 0f the bracket as shown in Figures 1 and 4, and. receivingslidably therein a bearing block 23 suitably grooved at top and bottomto receive therein lthe edge portionsof the bracket at the slot. It isdesirable, in order to minimize the thickness of metal required in thesebrackets, that ai reinforcing flange 24 be formed on the upper edge andalso one on the lower edge extending from the base or thereadjacent tonear the outer end of the bracket. An integral ear 25 is struck outwardfrom the bracket so as to form the inner end of the slot which ear istapped and threaded to receive a tension screw bearing on the block 23.The ear 25 is struck from the blank in a size greater than the majorvertical measure# ment of the bearing block 23, so that the latter maybe inserted from one side through the enlargement of the slot thusformed at its inner end and then moved into the outer part'. The upperand lower side portions of the. face of the bracket toward the base, and

thus afford a buttress support for the thrust sustained by the ear when`the bolt bears against the block 23.

A roller 26 similar to the one 20 before mentioned is mounted in theblocks 23 of the last mentioned two brackets, and around these two rollsthere is an endless belt or apron 27, the upper reach of which passesbetween the rolls 12-13 of the wringer, while the lower reach liesagainst the lower side of the lower roll of the wringer. Ordinarily insuch wringers there are no framing or other elements projecting abovetheplanes in which the lower reach ofthe apron moves.

The closing of the outer end of the slot prevents liability ofinexperienced persons hooked thereon is minimized or eliminated.`

The use of such appliances generally is well understood, together withthe advantages. ln my device, owing to the tact that wooden tramewringers have a fiat face on each oit the uprights, both at thereceiving' and delivery sides.7 the attachment of my brackets is asimple matter. In installing my device, it is only necessary to liftoutthe rolls in the way familiar in such devices, insert the lower throughmy apron 27 and then replace them as usual; after which the rollers 20and 26 are also inserted through the apron at respective sides of thevvringer and mounted in the brackets as indicated llt Will be seen thatthe brackets all lie between the planes of the upper and lovver reachesoic 4the apron so that there is a minimum liability of obstruction orabrasion ot Y fabrics.

accanto l claim:

1. As an improved article of manufacture,

a mounting bracket for an adjustable roller for endless beltscomprising@T a sheet metal body portion having a base for attachment toa support, and an arm part at right angles thereto having a longitudinalslot in the outer part, an earg at right angles to the body struckoutwardly from the body at the inner end ot the slot and of a widthgreater than that of the slot whereby the opening thus produced forms anenlargement of the slot, whereby to receive a bearingn block largervertically than the outer part of the slot and grooved to receive theedges of the slot when moved thereinto from said enlargement, said earbeing apertured to receive an adjusting screw therethrough.

2. The article of claim l in which the edges of the ear are bentoppositely from the slot and over the adjacent'body portion of the blockin abutment therewith to form buttresses. A

ln testimony whereof l aiiix my signature.
